Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to a database server expansion application. Background Art

[0002] A server is a type of computer that runs faster, has a higher load, and is more expensive than an ordinary computer. The server provides computing or application services to other clients (such as PCs, smartphones, ATMs, and even large devices such as train systems) in the network. The server must have a certain degree of "scalability" because the enterprise network cannot remain unchanged for a long time, especially in today's information age. If the server does not have a certain degree of scalability, it will not be able to cope with the increase in users. A server worth tens of thousands or even hundreds of thousands of dollars will be eliminated in a short period of time, which is unbearable for any enterprise. In order to maintain scalability, it is usually necessary to have a certain amount of scalability space and redundancy on the server.

[0003] Servers are usually installed in cabinets, and servers usually include various modules, such as CPU main control modules, storage modules, power modules, and cooling fan modules, etc. Different types of expansion modules need to be set up in the chassis. This expansion method only expands the operating modules of various servers, and cannot expand the cooling channel while expanding the server operating modules. The newly added server modules will affect the overall cooling efficiency inside the server cabinet.

[0004] For example, the Chinese utility model patent (application number: CN202221671205.9) discloses an "expansion server capable of rapid heat dissipation". Its specification discloses that: the server is the core component of a computer local area network, mainly running a network operating system, controlling and coordinating computing work between computers in the network, while the expansion server is a server used for expansion work and is applied to various network computing occasions;

[0005] However, the existing expansion servers have certain shortcomings when in use and need to be improved. First, the server generates a lot of heat when in use, and the overall heat dissipation and cooling of the server chassis causes the heat to easily stay in the chassis and cannot be quickly dissipated. Secondly, the heat after dissipation cannot be discharged in a centralized manner, causing the heat to accumulate in the server use room, so it cannot be effectively and quickly dissipated. The above patent can prove the defects of the prior art in the server expansion process mentioned in the background technology of this patent.

[0006] Therefore, we make improvements to this and propose a database server expansion application. Summary of the invention

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] In the scheme of this application:

[0028] 1. In order to solve the problem that the existing server expansion method in the prior art cannot expand the heat dissipation channel while expanding the server running module, and the newly added server module will affect the overall heat dissipation efficiency inside the server cabinet, the present application adds a refrigeration expansion module to the server host system, so that when the refrigeration expansion module is expanded inside the server running module, multiple heat dissipation channels can be added to the server, so as to ensure that when the server running module is expanded, the heat dissipation efficiency inside the server cabinet is improved simultaneously, and avoid the problem that the heat dissipation efficiency cannot keep up when the server running module is expanded;

[0029] 2. In order to solve the problem of low overall heat dissipation efficiency of the computer room where the cabinets are placed in the prior art, the present application sets up a closed cabinet, and the heat dissipation channel directly supplies cooling to the inside of the cabinet through the cooling and ventilation components. The cold air supplied to the inside of the cabinet does not exchange heat with the air outside the cabinet, thereby realizing that more server cabinets can be cooled on the basis of unchanged refrigeration equipment power; the cold air is guided from the bottom of the cabinet to diffuse upward from the bottom of the cabinet under the action of the exhaust fan inside the exhaust duct, and when the cold air passes through the server placed inside the cabinet, heat is exchanged with the server, so that the temperature of the server is reduced, and the synchronous expansion of the heat dissipation equipment and the server operation unit is realized;

[0030] 3. By rotating and setting the upper connecting plate and the lower connecting plate on the adjacent cabinets respectively, when the server needs to be expanded, the upper connecting plate and the lower connecting plate are rotated respectively and the two adjacent cabinets are brought closer to each other, so that the upper connecting plate and the lower connecting plate are connected to each other. After the connection, the upper connecting plate and the lower connecting plate together form a connecting channel for connecting the cooling and ventilation components. The two ends of the connecting channel are connected to the internal space of the adjacent cabinets respectively, so that the expansion of the server cabinet is realized, and the cooling and ventilation components are used to cool the inside of the server workspace formed after the expansion. Compared with cooling the entire computer room where the server is placed, this cooling and heat dissipation method is more efficient, can reduce the electricity required for refrigeration, and has a higher efficiency in converting energy into cooling of the server;

[0031] 4. By respectively arranging retractable telescopic pipes on both sides of the upper connecting plate and the lower connecting plate, after the cabinet is expanded, the pipe opening of the telescopic pipe moves toward the air inlet driven by the telescopic rod, which can automatically complete the connection between the cold air pipe and the internal space of the cabinet, so that the cabinet after expansion is connected to the interior of multiple telescopic pipes as a whole. At this time, the internal space of the cabinet is cooled along the cold air pipe and the telescopic pipe, which can efficiently cool the interior of the cabinet after expansion and improve the cooling efficiency of the cold air on the servers inside the cabinet;

[0032] 5. By setting filter components on both sides of the air inlet, the cold air entering between the upper connecting plate and the lower connecting plate can be filtered by the filter components and the diversion mesh plate at the same time, which can reduce the dust floating in the cold air and prevent the dust from floating into the cabinet and affecting the normal operation of the server and other equipment;

[0033] 6. By symmetrically arranging two groups of filter components on both sides of the air inlet, the filter components are rotatably connected to the lower connecting plate. When the external cooling device supplies cold air to the inside of the cabinet from the air inlet, the flowing cold air flow acts on the multiple rows of filter brushes, which can drive the installation plate to rotate, so that the installation plate adjusts the filter brushes at different positions to the position facing the air inlet, so that the dust floating in the cold air flow can be evenly attached to the multiple rows of filter brushes. In addition, since the upper end surface of the installation plate is inwardly concave in a funnel shape, it can prevent the dust falling on the installation plate from being blown by the cold air flow and falling from the installation plate, so that the dust collected inside the installation plate is more convenient to clean;

[0034] 7. By setting a drop hole at the center of the installation plate, the dust gathered in the center of the installation plate can easily fall to the bottom of the installation plate, the space below the installation plate will not be blown by the cold air flow, and the dust falling below the installation plate will not generate dust after accumulating to a certain height.

[0054] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0055] As described in the background art, the existing server expansion method cannot expand the heat dissipation channel while expanding the server operation module, and the newly added server module will affect the overall heat dissipation efficiency inside the server cabinet.

[0056] In order to solve this technical problem, the present invention provides a database server expansion application, which is applied to a server.

[0057] Specifically, please refer to Figure 1 , the database server expansion application specifically includes:

[0058] Multiple server hosts and refrigeration and ventilation modules, the refrigeration and ventilation modules include a refrigeration expansion module and a refrigeration control module;

[0059] The cooling control module is used to adapt cooling and heat dissipation when the server is expanded;

[0060] The server host includes a PCIE expansion module, a power supply module, and a storage expansion module; the PCIE expansion module is used to connect mechanical hard disk disk array cards, multi-interface network cards and other devices; the power supply module is used to power various electrical devices inside the server host; the storage expansion module is used to connect to the server to expand the storage space of the server.

[0061] As a preferred technical solution of the present application, the refrigeration expansion module is used to provide cooling to the interior of the server host and to cool down the interior of the server host. The refrigeration expansion module includes multiple refrigeration and ventilation ducts, and the multiple refrigeration and ventilation ducts are respectively connected to the interior of multiple server hosts.

[0062] As a preferred technical solution of the present application, it also includes a temperature control detection module, which is used to detect the temperature inside the server host and feedback to the refrigeration control module when the temperature inside the server host is too high. The refrigeration control module is used to control the temperature of the cold air blown to the server and the amount of cold air entering the cabinet.

[0063] As a preferred technical solution of the present application, the temperature control detection module also includes a network real-time monitoring module, which is used to detect the internal temperature of each server host in real time, and record the changes in the internal temperature of each server host at each time point, and when the temperature of a server host is abnormal, the data processed by the server host is backed up in time.

[0064] The present invention provides a database server expansion application. By adding a refrigeration expansion module to the server host system, the refrigeration expansion module can add multiple heat dissipation channels inside the server when the module expansion is running inside the server, thereby ensuring that when the server is running the module expansion, the heat dissipation efficiency inside the server cabinet is simultaneously improved, thereby avoiding the problem of heat dissipation efficiency not keeping up when the server is running the module expansion.

[0065] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0066] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0067] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0068] Example 1

[0069] Please refer to Figure 2 , Figure 3 As shown, a database server expansion application includes a frame 1 and a cabinet 2 of multiple servers slidably mounted inside the frame 1, and adjacent cabinets 2 are provided with a connecting component 3 for connecting the internal spaces of adjacent cabinets 2, and a cooling and ventilation component 4 is provided below the connecting component 3, and the cooling and ventilation component 4 is used to cool the inside of the connecting component 3 from both ends of the connecting component 3;

[0070] A ventilation frame 11 connected to the interior of the cabinets 2 is disposed on the top of the frame 1 . An exhaust duct 12 for exhausting the air inside the ventilation frame 11 is disposed on the upper end of the ventilation frame 11 . An exhaust fan is disposed inside the exhaust duct 12 .

[0071] An oil slide rail 13 is arranged inside the frame 1, and a plurality of cabinets 2 are slidably mounted on the slide rail 13 respectively. A plurality of support plates 21 are arranged inside each cabinet 2, and a support frame 22 for placing a computer server is arranged between the plurality of support plates 21.

[0072] It should be noted that when cabinet 2 is expanded, convection of cold and hot air occurs when cooling is provided to the interior of the newly connected cabinet 2. Water mist may be generated inside the newly connected cabinet 2 for a period of time. However, due to the continuous flow of cold air, the water mist will be carried away by the circulating cold air in a short time and will not affect the operation of the server host inside the cabinet 2.

[0073] By setting up a closed cabinet 2, the heat dissipation channel directly supplies cooling to the inside of the cabinet 2 through the cooling and ventilation component 4. The cold air used to cool the inside of the cabinet 2 does not exchange heat with the air outside the cabinet 2, so that the heat dissipation efficiency inside the cabinet 2 is higher, and more server cabinets 2 can be cooled on the basis of unchanged refrigeration equipment power; the cold air is guided from the bottom of the cabinet 2 to diffuse upward from the bottom of the cabinet 2 under the action of the exhaust fan inside the exhaust duct 12. When the cold air passes through the server placed in the cabinet 2, it exchanges heat with the server, so that the temperature of the server is reduced, and the synchronous expansion of the heat dissipation equipment and the server operation unit is realized.

[0074] Please refer to Figure 4 , Figure 5 , Figure 6 As shown, a database server expansion application, wherein the connecting component 3 includes an upper connecting plate 31 and a lower connecting plate 32 that are connected to each other, the upper connecting plate 31 and the lower connecting plate 32 together form a connecting channel, and both ends of the upper connecting plate 31 and the lower connecting plate 32 are provided with air inlets 301 for connecting to the cooling and ventilation components 4, and the end faces of the cabinets 2 that are close to each other are provided with rectangular through holes. When two adjacent cabinets 2 are separated from each other, the upper connecting plate 31 and the lower connecting plate 32 are respectively blocked on the rectangular through holes of the left and right cabinets 2 after rotation, thereby isolating the internal space of the cabinet 2 from the external air and preventing the outside air from entering the interior of the cabinet 2.

[0075] It should be noted that a telescopic member 35 for driving the upper connecting plate 31 or the lower connecting plate 32 to rotate is respectively provided inside different cabinets 2, and an adjusting rod 33 (such as Figure 3-Figure 5 as shown).

[0076] By rotating and setting the upper connecting plate 31 and the lower connecting plate 32 on the adjacent cabinets 2 respectively, when the server needs to be expanded, the upper connecting plate 31 and the lower connecting plate 32 are rotated respectively and the two adjacent cabinets 2 are brought closer to each other, so that the upper connecting plate 31 and the lower connecting plate 32 are connected to each other. After the connection, the upper connecting plate 31 and the lower connecting plate 32 together form a connecting channel for connecting the cooling and ventilation components 4, and the two ends of the connecting channel are respectively connected to the internal space of the adjacent cabinets 2, so as to realize the expansion of the server cabinet 2, and cool the inside of the server workspace formed after the expansion through the cooling and ventilation components 4. Compared with the overall cooling of the computer room where the server is placed, this cooling and heat dissipation method is more efficient, can reduce the electricity required for refrigeration, and has a higher efficiency in converting energy into cooling of the server.

[0077] Example 2

[0078] A database server expansion application provided in Example 1 is further optimized, specifically, as follows: Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the cooling and ventilation assembly 4 includes a cold air duct 41 installed on the side of the cabinet 2, and a telescopic duct 42 for conveying cold air is provided at one end of the cold air duct 41 facing the air inlet 301, and telescopic rods 43 for driving the telescopic duct 42 to be telescopic are provided on both sides of the cold air duct 41, and an annular sealing plate 44 for pressing against the air inlet 301 for sealing is provided at one end of the telescopic duct 42 close to the air inlet 301, and the telescopic rod 43 drives the telescopic duct 42 to be telescopic by driving the annular sealing plate 44 to move.

[0079] Ear plates 45 for connecting to the telescopic rod 43 are provided on both sides of the annular sealing plate 44, and sealing gaskets are provided on the ear plates 45 toward the air inlet 301. When the annular sealing plate 44 is attached to the side of the air inlet 301, the sealing gaskets on the ear plates 45 are blocked at the intersection of the upper connecting plate 31 and the lower connecting plate 32, thereby sealing the intersection of the upper connecting plate 31 and the lower connecting plate 32.

[0080] By respectively arranging retractable telescopic ducts 42 on both sides of the upper connecting plate 31 and the lower connecting plate 32, after the cabinet 2 is expanded, the pipe mouth of the telescopic duct 42 moves toward the air inlet 301 driven by the telescopic rod 43, which can automatically complete the connection between the cold air duct 41 and the internal space of the cabinet 2, so that the cabinet 2 after expansion is connected to the interior of multiple telescopic ducts 42 as a whole. At this time, the internal space of the cabinet 2 is cooled along the cold air duct 41 and the telescopic duct 42, and the interior of the cabinet 2 after expansion can be efficiently cooled, thereby improving the cooling efficiency of the cold air on the server inside the cabinet 2.

[0081] Further, such as Figure 4-Figure 9 As shown, the filter assembly 5 is also rotatably arranged on the lower connecting plate 32 , and the filter assembly 5 is used to filter dust in the cold air entering from the air inlet 301 . A diversion mesh plate 56 can also be detachably installed between the upper connecting plate 31 and the lower connecting plate 32 .

[0082] By setting filter components 5 on both sides of the air inlet 301, the cold air entering between the upper connecting plate 31 and the lower connecting plate 32 is filtered by the filter components 5 and the diversion mesh plate 56 at the same time, which can reduce the dust floating in the cold air and prevent the dust from floating into the cabinet 2 and affecting the normal operation of the server and other equipment.

[0083] Example 3

[0084] A database server expansion application provided in Example 1 or 2 is further optimized, specifically, as follows: Fig.10 , Fig.11 As shown, the filter assembly 5 is provided with two groups, and the two groups of filter assemblies 5 are symmetrically installed on both sides of the inlet 301. Each group of filter assemblies 5 includes a mounting plate 51 rotatably mounted on the lower connecting plate 32. A plurality of rows of filter brushes 52 are arranged in a ring shape on the mounting plate 51, and the upper end surface of the mounting plate 51 is concave inwardly and funnel-shaped.

[0085] By symmetrically arranging two groups of filter components 5 on both sides of the inlet of the air outlet 301, the filter components 5 are rotatably connected to the lower connecting plate 32. When the external cooling equipment supplies cold air to the inside of the cabinet 2 from the air inlet 301, the flowing cold air flow acts on the multiple rows of filter brushes 52, which can drive the mounting plate 51 to rotate, so that the mounting plate 51 adjusts the filter brushes 52 at different positions to a position facing the air inlet 301, so that the dust floating in the cold air flow can be evenly attached to the multiple rows of filter brushes 52. In addition, since the upper end surface of the mounting plate 51 is concave inwardly and funnel-shaped, the dust falling on the mounting plate 51 can be prevented from being blown by the cold air flow and falling from the mounting plate 51, which can make it more convenient to clean the dust collected inside the mounting plate 51.

[0086] Further, such as Figure 4 As shown, a dropping hole 5101 for dropping dust is provided in the middle of the mounting plate 51, and a connecting shaft 55 connected to the inner wall of the dropping hole 5101 is provided in the middle of the dropping hole 5101. The lower part of the connecting shaft 55 is rotatably connected to the lower connecting plate 32. A gap is left between the mounting plate 51 and the lower connecting plate 32 for dust to fall, and the position of the mounting plate 51 is not higher than the lowest point of the air inlet 301.

[0087] By setting a drop hole 5101 at the center of the mounting plate 51, the dust gathered in the center of the mounting plate 51 can easily fall to the bottom of the mounting plate 51, and the space below the mounting plate 51 will not be blown by the cold air flow. The dust that falls below the mounting plate 51 will not generate dust after accumulating to a certain height.

[0088] Further, such as Fig.13 As shown, the bottom of the mounting plate 51 is provided with an arc-shaped paddle 54 in a circular shape. The paddle 54 is used to pry the dust below the mounting plate 51 , and the inner arc surface of the paddle 54 faces the rotation direction of the mounting plate 51 .

[0089] It should be noted that the rotation speed of the mounting plate 51 driven by the cold air flow is very low, and the dust dropped on the lower connecting plate 32 will not be raised.

[0090] By arranging a paddle 54 at the bottom of the mounting plate 51, the dust dropped under the mounting plate 51 can be conveniently collected under the dropping through hole 5101. In addition, a collecting groove 3201 is arranged under the dropping through hole 5101. When the paddle 54 rotates with the mounting plate 51, the dust under the mounting plate 51 can be conveniently collected into the collecting groove 3201, so that the staff can conveniently collect the gathered dust when cleaning the dust between the upper connecting plate 31 and the lower connecting plate 32.

[0091] Further, such as Fig.11 , Fig.12 As shown, the outer peripheral surface of the mounting plate 51 is provided with a plurality of sliding grooves 5102, and an impact assembly 53 is slidably installed inside each sliding groove 5102. The impact assembly 53 includes an impact rod 531, and one end of the impact rod 531 inserted into the sliding groove 5102 is provided with a tension spring 532 for limiting the impact rod 531 inside the sliding groove 5102.

[0092] By arranging a plurality of impact assemblies 53 on the outer peripheral surface of the mounting plate 51, as the dust floating in the cold air flow is adsorbed on the filter brush 52, the filter brush 52 will have a greater hindering effect on the cold air flow. At this time, the filter brush 52 will drive the mounting plate 51 to rotate faster, causing the impact rod 531 of the impact assembly 53 to be thrown out from the inside of the sliding groove 5102. The thrown-out impact rod 531 will hit another mounting plate 51 placed oppositely, causing the other mounting plate 51 to vibrate (the mounting plate 51 is hollow inside), which can make this mounting plate 51 make a sound, and this sound can be used to remind the staff to clean the filter assembly 5.

[0093] In addition, during actual use, by increasing the cooling power of the external cooling equipment, the flow rate of the cold air flow from the air inlet 301 into the space between the upper connecting plate 31 and the lower connecting plate 32 can be accelerated. At this time, when the cold air flow acts on the filter brush 52, the rotation speed of the mounting plate 51 can also be made faster. By making the rotation speed of the mounting plate 51 faster, the impact rod 531 on the side of the mounting plate 51 can be thrown out, so that the impact rod 531 hits another mounting plate 51 on the side, and then the mounting plate 51 vibrates, and the dust attached to the filter brush 52 above the mounting plate 51 falls into the inside of the mounting plate 51, so as to achieve the purpose of simply cleaning the filter brush 52. When it is inconvenient to take out and clean the filter brush 52, it can be cleaned in this way.

[0094] The multiple rows of filter brushes 52 on the mounting plate 51 gradually decrease in length from outside to inside, so that the multiple rows of filter brushes 52 on the mounting plate 51 present a centrally concave shape as a whole, so that the outer filter brushes 52 can be subjected to greater wind force, and the wind sprayed from the air inlet 301 can more easily blow the mounting plate 51 to rotate.

[0096] A database server expansion application provided in Example 1 or 2 is further optimized. Specifically, please refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a wiring assembly 6 for connecting the connecting lines of the servers inside the cabinet 2 is provided between the upper connecting plate 31 and the lower connecting plate 32. The wiring assembly 6 includes a first wiring box 61 installed on the upper connecting plate 31 and a second wiring box 62 installed on the lower connecting plate 32. The first wiring box 61 installed on the upper connecting plate 31 and the second wiring box 62 installed on the lower connecting plate 32 are close to each other when the upper connecting plate 31 and the lower connecting plate 32 are connected to each other. The end surfaces of the first wiring box 61 and the second wiring box 62 that are close to each other are provided with wiring heads and wiring slots. When the first wiring box 61 and the second wiring box 62 are connected, the wiring head of the first wiring box 61 is inserted into the wiring slot of the second wiring box 62. The specific structures of the above-mentioned wiring heads and wiring slots are all existing technologies and will not be repeated in this application document.

[0097] The first wiring box 61 and the second wiring box 62 are both provided with a plurality of wire access through holes 601 , and the server connection wires inside the cabinet 2 pass through the plurality of wire access through holes 601 and are connected to the wiring heads inside the first wiring box 61 and the second wiring box 62 .

When the push rod 46 follows the annular sealing plate 44 to approach the upper connecting plate 31, the push rod 46 passes through the sliding through hole and pushes the sliding plate 63 to move toward the first terminal box 61 and the second terminal box 62, so that the clamping plate 65 is clamped on both sides of the first terminal box 61 and the second terminal box 62.

[0099] By slidingly setting a sliding plate 63 on the upper connecting plate 31, and setting a push rod 46 on the annular sealing plate 44 to extend into the interior of the upper connecting plate 31, the sliding plate 63 is pushed toward the first wiring box 61 and the second wiring box 62 by the push rod 46, so that the clamping plate 65 is clamped on both sides of the first wiring box 61 and the second wiring box 62, the connection of the connecting lines of the servers inside the two adjacent cabinets can be made more stable. In addition, since the first wiring box 61 and the second wiring box 62 are respectively installed on the upper connecting plate 31 and the lower connecting plate 32, after the docking point between the first wiring box 61 and the second wiring box 62 is stable, the docking between the upper connecting plate 31 and the lower connecting plate 32 is also more stable.

[0100] Furthermore, if Figure 3 , Figure 4 , Fig.14 As shown, a fire extinguishing assembly 7 for extinguishing a fire inside the cabinet 2 is also provided between the two adjacent cabinets 2. The fire extinguishing assembly 7 includes a storage cylinder 71 for storing an inert gas. Both ends of the storage cylinder 71 extend into the interior of the two adjacent cabinets 2 respectively. Nozzles 75 for spraying inert gas into the interior of the cabinet 2 are provided at two points of the storage cylinder 71 respectively. The outer sides of the storage cylinder 71 are respectively engaged with the two adjacent cabinets 2.

[0101] It should be noted that the side projection shape of the storage cylinder 71 is gear-shaped, and a motor 72 for driving the storage cylinder 71 to rotate is provided on the middle side of the storage cylinder 71, and the motor 72 drives the storage cylinder 71 to rotate through the driving gear 73. The part of the outer circumference of the storage cylinder 71 extending into the interior of the cabinet 2 is provided with a snap-in notch 712, and the interiors of the two adjacent cabinets 2 are both provided with a fixing plate 74 for snapping on the outside of the snap-in notch 712, and the fixing plate 74 is provided with a snap-in through hole 741 for the storage cylinder 71 to pass through, and the shape of the snap-in through hole 741 is consistent with the shape of the outer circumference of the storage cylinder 71, and a snap-in block 742 is provided inside the snap-in through hole 741, and a telescopic rod is used above the snap-in block 742 to control the approach or distance to the snap-in notch 712 of the storage cylinder 71.

[0102] By setting the motor 72 to drive the storage cylinder 71 to rotate, the outer wall of the storage cylinder 71 can be engaged with the fixing plate 74. In addition, during the fire extinguishing process, the motor 72 can also be used to adjust the orientation angle of the nozzle 75. According to the fire position sensed inside the cabinet 2, the nozzle 75 is adjusted to accurately aim at the fire source, so as to achieve the purpose of rapid fire extinguishing (when the flame sensor inside the cabinet 2 senses the occurrence of a fire, it will control the cooling and ventilation components 4 on both sides of the cabinet 2 to stop cooling the inside of the cabinet 2, so as to prevent external oxygen from entering the cabinet 2 and accelerating the fire);

[0103] In addition, a rotating connecting disk 76 for the storage tube 71 to pass through is rotatably provided on the side wall of the cabinet 2, and the outer edge of the rotating connecting disk 76 is rotatably sealed and connected to the side wall of the cabinet 2; a plurality of flame sensors are arranged inside the cabinet 2, and the flame sensors are distributed at various positions inside the cabinet 2 at intervals.
